The utility model has the beneficial effects that
The tool for fishing coiled tubings of the hydraulic-driven at work, will be on the oil pipe that salvaged under tool to predetermined needs
Side, when continuing decentralization tool, guide shoe is by inclined fish righting, and impeller shaft drives column type junk mill to deformation under hydraulic-driven
Fish fish head carries out milling, so that tool can smoothly enter into inside fish.After internal slip is all introduced into inside fish,
Piston is pushed by the pressurizing port on central axis, drives internal slip sliding block that internal slip opening is close to fish inner wall.Upper
During mentioning, spiral slips on outer cylinder because the vertical section of wide buttless thread is tapered slope, slips with heavy fish to
The conelet end motion of cone, fish weight is cured kilocalorie and obtains also tightlier at this time.Interior external slips synergy improves the reliable of salvaging
Property, salvaging efficiency is so effectively increased, secondary salvaging is avoided.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the internal slip structural schematic diagram of the utility model.
The spiral kava structure schematic diagram of the position Fig. 3 the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Dual-grip reversible coiled tubing fish fishing tool as shown in Figure 1:, mainly by nipple 1, piston 4, compression
Spring A 3, compressed spring B 6, internal slip 9, impeller shaft 12, column type junk mill 14, guide shoe 15, spiral slips 19, outer cylinder 20, center
Axis 21, top connection 23 are constituted.
Nipple 1 is connected through a screw thread with 21 upper end of central axis, there is pressurizing port 22 on front side of central axis 21.On central axis 21 according to
It is secondary to be equipped with piston 4, spring pocket 8, internal slip sliding block 18, internal slip 9 (as shown in Figure 2), internal slip seat 17 and B sheath 10；
Internal slip seat 17 and central axis 21 are positioned by shoulder, and there is runner 16 in 21 bottom end of central axis.
A compressed spring 3 and piston bush 2 are housed on piston 4；
B compressed spring 6,6 other end connecting spring block 7 of B compressed spring, 6 peripheral hardware of B compressed spring are housed on spring pocket 8
It is equipped with A sheath 5.
It is connected between B sheath 10 and impeller shaft 12 by bearing group 11.12 upper end of impeller shaft is in turbine leaf sheet, impeller shaft
12 are threadedly coupled with column type junk mill 14, and central axis 21, B sheath 10 have cavity between impeller shaft 12, equipped with upper on the outside of nipple 1
Connector 23, tool consists of inside and outside two parts, and is threadedly coupled with top connection 23 with outer cylinder 20.Spiral slips 19 is housed inside outer cylinder 20,
The fishing tooth of grabbing of wide buttless thread and inner face outside spiral slips 19 is left hand thread (as shown in Figure 3), is matched with outer cylinder 20
The gap of conjunction is larger, and spiral card watt 19 can be enable to have certain stroke to swell and reduce in outer cylinder 20.
20 other end of outer cylinder is threadedly coupled with guide shoe 15, and guide shoe 15 can replace different model.
The working principle of the utility model are as follows:
When salvaging fish, predetermined position will be arrived under tool, that is, above fish to be salvaged.Firstly, will be inclined by guide shoe 15
Fish righting；Secondly, rotating using fluid driven impeller axis 12 with moving column type junk mill 14, milling is carried out to the fish fish head of deformation
Finishing, so that tool can enter inside fish；Finally, fluid passes through center after internal slip 9 fully enters fish inside
Pressurizing port on axis 21 pushes piston 4 and compressed spring A 3, and then pushes 17 downlink of internal slip sliding block, and internal slip 9 is pushed away completely
It opens, is tightly attached to the anchor fluke tooth on internal slip 9 on the inner wall to fishing oil pipe 13, complete internal clamping process.
During above mentioning, the specific rotation direction tooth form thread in 19 inside of spiral slips in outer cylinder 20 can be by fish clamping.This
Sample is during salvaging, interior external slips synergy, so that salvaging steady reliable.When salvaging is completed to exit tool, it is only necessary to subtract
The pressure of fluid can withdraw internal slip 9 in small central axis 21, and tool is smoothly exited fish.
